Cross connection

What does 3181 mean?

The drive has detected an incorrect connection between the input power cables and the motor cables, specifically if the input power is connected to the motor output terminals. This is a critical wiring error that will trip the drive to prevent severe damage to the power unit and motor due to incorrect voltage application.
